DETAILED DESCRIPTION OF THE INVENTION

While this invention may be embodied in many different forms, there aredescribed in detail herein specific preferred embodiments of theinvention. This description is an exemplification of the principles ofthe invention and is not intended to limit the invention to theparticular embodiments illustrated.

For the purposes of this disclosure, like reference numerals in thefigures shall refer to like features unless otherwise indicated.

FIGS. 1A and 1B depict the phone with the antenna collapsed from a sideand front view. The basic mechanical components of the phone 10 are thespeaker and speaker section 12, the antenna 14, and the microphonesection 18. The center section 19 carries the batteries and theelectronics. It also serves as the base for the “911” button 16.

A spring 20 to automatically deploy the antenna is shown in the speakersection. In an alternative embodiment, the antenna is slid down into thephone body with a linear spring. When the 911 button is pushed, itreleases the antenna, which then slides out the end into a fullyextended position when released.

In one embodiment, the whole phone is made waterproof through the use ofwaterproof switches, microphone, and speakers.

FIG. 2 shows the identical components but with the antenna extended. Theoperation of the spring is such that the antenna is normally fullyextended.

FIG. 3 shows the phone of this embodiment in its weatherproof pouch 30.This pouch could be made of any water or weatherproof material includingvinyl, polycarbonates or other polymers. Along the front end of thepouch 30 is an embedded quick release strip 34, which has a brightlycolored large pull tab 36. For use of the phone the tab 36 is grippedand pulled down the complete length of release line 34 to open the pouchand access the phone. This then automatically deploys the antenna due tothe operation of the integral spring.

On the back of the phone pouch 30 is an attachment means. In thepreferred embodiment this is shown as a Velcro® type of mechanism 32.Alternatively it could be suction cups for glass or adhesives for metal.Further alternatives would include magnets for metal. The Velcro® worksparticularly well for the roof cloth or floor carpeting of many cars.Yet another alternative attachment mechanism would be a combination ofVelcro® and magnet for universal attachment as shown using the magnets38 embedded in the pouch.

The pouch is transparent to make the phone contents very obvious in anemergency situation.

Due to the presence of dedicated integrated circuits the electronicportion of a conventional cellular phone design is doable by anyoneskilled in the art of electrical engineering. The circuit in FIG. 4 ismeant to be broadly illustrative. The circuitry is not meant to be ingreat detail as that is no longer necessary with this art. Speaker 40 iscoupled through capacitors 42 and 44 to audio controller 60. The audiocontroller 60 receives a demodulated audio line 62 from the RF sectionchip 66. That RF section chip receives the RF signal from antenna 68.Microswitch 17 is shown connected to the power supply chip forautomatically turning on the phone after the antenna is deployed asshown in FIGS. 1 and 2.

Microphone 46 is coupled through capacitors 48 and 50 and resistors 52,54, 56, and 58 into the audio controller 60. The audio controller thensends the “audio out” signal on line 64 into the RF section 66 for finaltransmission out on antenna 68. When the call button 16 is depressed themicroprocessor microcontroller 70 interprets this and activates theappropriate sequences and the digital controller 72 would then give theappropriate controls to the audio controller 60. Digital controller 72is clocked by a crystal oscillator comprising capacitors 74 and 76,crystal 78, and resistor 80. All of the electronic components arepowered by battery 76 through the power supply chip 74. A representativeaudio controller is the TCM 8010 of Texas Instruments, P.O. Box 655303,Dallas, Tex. 75265. A representative RF section IC is the TRF 1015 fromTexas Instruments. There are numerous manufacturers of microprocessorsor microcontrollers. Sample devices are the 8051 or 8032 available fromnumerous electronic manufacturers. electronic manufacturers. Arepresentative of the digital controller is the TCM 8002 from TexasInstruments. Representative power supply ICs are the TPS9013 or theTPS9104, both of Texas Instruments.

The battery 76 is a permanently installed primary cell such as analkaline, lithium, or manganese dioxide cell although many other typescould work. The cell must provide high peak currents in transmission butotherwise is not required to have extremely high longevity. By having apermanent primary cell there is an economy over the use of an expensiverechargeable cell and also over the use of a changeable primary cell dueto the expense of the battery holders chambers and doors. These batteryholders, chambers, and doors for a battery chamber also introducereliability problems. As an alternative embodiment the battery could bea fixed or removable thermal battery or any practical battery.

Microswitch 17 is activated by the antenna springing out and thusautomatically turning on the device. FIG. 5 depicts the circuitmodifications to allow for the automatic crash activation feature. Thethree-axis acceleration sensor 100 will detect the sudden accelerationfrom a crash and pass this on to three-channel amplifier 102 and then onto the microprocessor and microcontroller 70. If a sufficient force isdetected then the device will turn on automatically and begin pulsingthrough transistor 104 to pulse integral light 106. The light 106 isalso used to light up the 911 button after the antenna is deployed. Themicroprocessor microcontroller will also signal the rapid beepingthrough the phone speaker 40, which is shown in FIG. 4.

If the phone is not operated within 5 minutes of the “crash” then itautomatically turns off to save battery life. Alternatively the phonecould include a “hang-up” button which could also stop the flashing andpulsing.

Suitable acceleration sensors are available from Analog Devices ofNorwich, Mass.

FIG. 6 shows the flow chart for the operation of the phone withparticular attention to the unique feature that allows the operation ofthe phone without the customer having to pay a monthly access fee for aprivate number.

The provider (distributor) of the disposable emergency cellular phoneswill pay a monthly fee for a few phone numbers. Each of these phonenumbers (mobile identification number [MIN]) comes with an electronicserial number (ESN) which will be transmitted with the MIN in order toregister to the cellular system. (A conventional cellular phone alsotransmits its MIN and a unique ESN, which it registers. The ESN isunpublished and is matched with the phone to minimize fraudulent usage.)One feature of this invention is that thousands of the disposableemergency phones could share a small set of MINs and matching ESNs.

Assume that the average call requires 5 minutes. The table below givesthe number of MINs required for a smoothed (average) load as a functionof the number of subscribers. The last column gives the estimated numberof MINs required to reduce waits as call volume will not be perfectlyconstant.

number of MINs needed for MINs needed to subscribers average loadminimize waits 100 1 3 200 1 5 500 2 8 1,000 4 12 2,000 7 17 5,000 18 3010,000 35 49 20,000 70 85 50,000 174 190 100,000 348 364 200,000 695 712500,000 1,737 1,753 1,000,000 3,473 3,490 2,000,000 6,945 6,9625,000,000 17,362 17,378 10,000,000 34,723 34,740

In operation, the first step is to wait for the 911 button depression200. Step 202 is to register with a MIN and ESN. Step 204 is to verifythat registration (log on) is established. If it is established then themethod proceeds on to step 206 which is to transmit the 911 number. Thenstep 208 begins a timer. Finally, at step 210 the device will disablefurther transmissions when the timer reaches 60 minutes. In analternative embodiment, a counter is used to limit the number of 911calls to a small fixed number, say 5. The total talking time would thenbe limited only by the battery life and the patience of the 911operators. If at step 204 registration was not established then themethod proceeds to step 212, which is to verify that a carrier signal ispresent. If If no carrier is detected then the method returns to step202 to attempt registration again. If the carrier is detected then themethod proceeds to step 214 and increments to the next MIN (phonenumber) and ESN (serial number). It then attempts another registrationin step 216. The reason for the attempt for different numbers is that itis conceivable that two customers would both be trying to make a 911call at the exact same time. Were that to occur, the first caller wouldnormally lock out that number nationwide and prevent the second callerfrom getting through. Thus a disposable cellular phone provider wouldhave a few numbers that a minimal monthly service fee is paid for. Thesystem could try the MINs and ESNs (phone and serial numbers) in a fixedsequence or a random fashion. Alternatively the phone could simply logon with a public phone number and transmit a 311 or 911 call since theFCC requires phone companies to accept 311 and 911 calls regardless ofthe account status.

FIG. 7 shows the physical embodiment of the stun gun in this version ofthe cell phone. The basic phone 300 has a conventional key pad 302 andread-out display 304 along with the antenna 306. There is also theon-off button 308 as standard.

There is a left side high (mechanical) resistance push button 310 toenable the flashlight. Also there is a right side push button 311 toenable the electrical stunning operation when used in conjunction withthe switch 310. When the flashlight is enabled then the battery from thecell phone is connected to high intensity light bulb 312. When bothswitches 310 and 311 are enabled simultaneously a high voltage isdeveloped between the pseudo antenna tip 314 and the tip of the normalantenna 316. The angle between the tips 314 and 316 is very important asit allows the shock to be delivered from the operator's right hand andangled to attack the arm or hand of an attacker without having to have afull perpendicular contact.

FIG. 8 shows the synergistic operation of the circuitry. We begin withthe battery 320, which is connected to the conventional cell phonecircuitry 322, which then drives the conventional antenna 306 fortransmission. When switch 311 is depressed then the battery power 320 isdelivered directly to the light bulb 312 to cast an intense beam.

When both switches 311 and 310 are depressed then battery current isdelivered to oscillator 324. Oscillator 324 provides an AC current totransformer 326 which develops a high voltage output which is rectifiedby diode 328 and stored in capacitor 330. In this way a voltage is builtup to over 1000 volts on capacitor 330. When the voltage exceeds 1000volts on capacitor 330 then the hermetically sealed spark gap 332 willbreak down and deliver a short intense current through transformer 334.The output of transformer 334 (of about 25,000 to 50,000 volts) willthen appear between contacts 306 (which is the conventional antenna) and314 which is the shocking probe “pseudo antenna.” The hermeticallysealed spark gap 336 limits that voltage to prevent damage to thecircuitry. The Zener diodes 337 serve to protect the cell phonecircuitry from the effects of this high voltage and keep the antenna 306closer to a ground potential.

Another key element of this invention is the use of a thermal batteryfor an emergency phone system. U.S. Pat. No. 6,041,255 teaches thepossible use of a thermal battery for a single use externaldefibrillator.

The detailed construction of the piles of a thermal battery is shown inFIG. 9. It begins with a pyrotechnic heat source 340 which is followedby cathode 342 which is followed by an electrolyte 344, followed byanode 346 followed by current collector 348. The electrolyte at normalambient temperature is a solid, insulating inorganic salt. Theelectrolyte is rendered molten by the pyrotechnic heat source. The heatmelts the electrolyte which causes it to be conductive and deliverelectrical power at an extremely high rate. The thermal battery has manyattributes making it ideal for an emergency phone system. First, it hasno leakage current until it is triggered. Thus it has a shelf life often or twenty years. It then delivers current at an extremely high ratefor a short period of time on the order of minutes. This is ideal forlong range, high power transmission.

Representative materials for the battery anode include lithium, calcium,magnesium, and others. The electrolytes that have been used successfullyin these batteries have been lithium chloride and potassium chloridemixtures primarily. Representative cathodes are FeS₂, K₂Cr₂O₇, WO₃,CaCrO₄, and V₂O₅ for example. A typical pyrotechnic heat source is ironwith KClO₄.

FIG. 10 shows the overall construction of a thermal battery. Batterypiles 350 are shown stacked as discs leaving an open core 354. Theelectric match 352 is placed above that open core. Electric match 352 isignited by current passing through contacts 358 and 360. Connection 356is used for delivery of current from the battery and the other currentdelivery connection can be one of the match terminals, either 358 or360. As an alternative, yet a fourth electrode could be used for thebattery output current. Insulation material 364 is wrapped around thebattery to keep it very hot so that it can achieve its high levels ofefficiencies. Temperatures on the order of 23° Celsius are not uncommon.Representative insulation that can be used include Mica, silicon-bondedMica, FiberFrax, Microtherm, Aluminum/Mica combinations, and Min-K.

In the embodiment using an electric match to trigger the thermalbattery, a conventional non-thermal small battery such as a lithiumbattery will deliver current when connected through the electric matchcircuitry. This will cause the thermal battery to go to its hightemperature mode and then deliver current at an extremely high level.

Another preferred embodiment for this invention is shown as FIG. 15 of“Thermal Battery Booster System” Ser. No. 09/504,500, filed Feb. 15,2000. In this case the electric match is replaced by a percussionignitor. This is essentially a primer from a shotgun shell. This has animpact activated explosive. A spring loaded percussion ignition systemcomprising a firing pin and spring (or other mechanical activationmeans). Then the firing pin will contact the percussion ignitor to beginthe thermal battery ignition process. This will then allow the thermalbattery to begin delivering extremely high currents without the need foran electric match and small triggering battery.

FIG. 11 shows the method of operating the thermal battery emergencyphone. We begin at step 400, which is to activate the phone. At step 402the base station carrier is attempted to be detected. If the basestation carrier is detected then we go to step 404 which is to proceedas in FIG. 6 to register. If the base station carrier is not detected instep 402 then we go to step 406 and the system asks if the number 911was dialed. If it was not then we go to step 408 which warns that only911 calls can get through with the high-power operation at this pointand returns to step 406. If 911 was, in fact, dialed then the systempermits the move to step 410 which is to go to unrestricted mode inwhich case it will scan all carriers and frequencies. Thus if thesubscriber's main provider was the local System A which is unavailableit could also allow System B as well as other frequencies. At step 412the system looks for a base station carrier to be detected. If it is,then it would proceed as in FIG. 6 before. If it is not then the systemproceeds to step 414 at which point the thermal battery is activated andthe system goes to a maximum power transmit level of 20 watts. This isimportant as a thermal battery is able to provide at least 20 watts ofoutput power, or even up to 50 watts but only for a watts but only for ashort period of time. Thus the output power is merely limited by theoutput stage transistors and a significant increase in range would beobtained. The conventional cell phones are limited to three-watt powerand thus, for this emergency operation, an output of 12 watts gives anincrease of four times which would give a doubling of the range by thesquare power law.

The invention of using multiple MINs and ESNs for a generic number phonesystem has many uses beyond the emergency cellular voice phone. Some ofthese embodiments are described below.

The set of MINs and ESNs for a given set of phones would be stored inthe memory of each of the phones. The provider can download additionalnumbers to generic phone number customers if it is found that they areexperiencing excessive waits.

FIG. 12 shows the operation of the generic number phone for sending andreceiving local data. The subscriber unit could be a laptop computer, apalmtop computer, a personal digital assistant, a cellular phone with asufficient display to read Email, or other means of entering ordisplaying digital messages. It could be a car computer with a digitaldisplay terminal. The exact hardware system is quite flexible. Theoperation begins in step 420 where the operator activates the mobiledata phone. At step 422 the selection is made to send or receive data.If the decision is made to send data then the system proceeds to step424 and asks if the data is ready for transmission. If it is then thesystem proceeds to step 430 which it would also go to if it was ready toreceive data. If at step 424 the system is not ready to transmit datathen it goes to step 426 where it opens an email screen for theoperator. At this point the operator must at step 428 prepare the emailmessage. When this is ready then everything goes to step 430 where thesystem will attempt a registration with a randomly chosen mobileidentification number MIN_(j) and an electronic serial number ESN_(j).These numbers are not capriciously chosen but are rather from the listof approved numbers for this service. At step 432, if the system findsthe registration was unsuccessful due to the fact that someone else wasusing that mobile identification number and that serial number, then thesystem goes to step 434. At that point j is increased by 1 and thesystem goes back to step 430 to attempt registration with the nextMIN_(j) and ESN_(j). When registration is finally successful then thesystem proceeds to step 436 where it will send and receive data. Afterthe data is sent or received the system proceeds to step 438 which is tohang up.

FIG. 13 shows the on/off times that are available when an operator typesa four digit number. In this case the operator has typed in a PIN or asubscriber's line number of 5678. This operation generates eightdistinct times beginning with the “space” time T10, which is the timefrom the prompt or previous number to the pushing of the “5” key.

Then there is the “key-down” time T11 which is the amount of time the“5” key is held down, etc.

This set of times provides a distinct signature of the operator due tothe fact that everyone has different typing habits. This is the subjectof co-pending application Ser. No. 08/942,820, “ATM signature securitysystem” filed Oct. 2, 1997. The operation of this security system isshown in FIG. 14 and also later on in FIG. 17 as one application.

In FIG. 14 we begin with step 500 which measures space times and keydown times during entry of a phone or PIN. Step 502 of the systemtransmits the vector of times 504 to the base station which selects thestored signature acceptance criteria based on the type of phone beingused. In step 506 the transmitted vector is compared to the existingsignature range. In step 508 the comparison results are acted on. If thetransmitted vector of times is found to be within limits then the callor transaction is approved at step 510. Then at step 512 the vector isused to update the stored signature slightly to account for aging orchanging of patterns of the user.

If, at step 508, the vector was out of limits then the customer is askedto reenter the number at step 514. The vector is then compared to thestored signature at step 516 and if it is then found within limits thenthe operation proceeds to step 510. If the vector is found to be outsideof limits for the second time then the system goes to step 518 toinitiate the emergency procedure.

An important alternative embodiment to the system as shown in FIG. 14involves comparing the signature internally at the phone at step 508rather than at the base station. This would allow the phone to bemodified and not require modification of base stations. The disadvantageis that one could perhaps fraudulently modify phones.

FIG. 15 shows the application of this generic number cellular telephoneto monitor people. This could be a criminal in house arrest or a child.The step 530 is to attach a phone to monitor a person with a tamperproofmeans. Step 532 is pseudo random number generator, which generatesrandom call times. This is to prevent a sophisticated criminal fromhaving a scanner, or other sense of detection of a cellular phonetransmission, detecting when the cell phone is making a transmission andassuming that he or she is free to move about in between. The pseudorandom number generator would randomly generate call times between oneminute and several hours of each other.

In step 534 the location of the call is recorded at a monitoring basestation as the call comes in. This location could be generated by moderncellular location systems from “enhanced 911” service or could use eventhe simpler version, which simply gives the cellular antenna involved.The more sophisticated but expensive system would involve the use of GPSreceiver including the monitor. This has a disadvantage of being unableto report when someone is indoors so the GPS system would have to storethe most recent good GPS data. To prevent the fraud of having thecriminal cover the GPS antenna to allow movement the system would havethe backup of noting the base cellular antenna to demonstratesignificant movements.

Finally at step 536 authorities are alerted if the monitored person isin an inappropriate location. This is done by the base station makingappropriate calls that could also be done automatically from theattached cellular phone on the monitored person.

Similarly, this invention will be very useful for the monitoring ofstolen cars. When circuitry in the car detects that the car is beingmoved by unauthorized people, then the generic phone number cellularphone will begin transmitting this fact along with location information.Also, by differentiating the position information, the system cancalculate the direction of heading and forward all of this to theauthorities.

FIG. 16 shows the method of this invention for medical monitoring. Itbegins at step 540 recording diagnostic information. This could be froman implantable device or an external monitor or a nerve stimulator, etc.

It then moves to step 542 and asks if the information suggests anemergency. If it suggests an emergency then it proceeds to step 544 tocall 911 as done in the method shown in FIG. 6. The system then, at step546, generates a recorded (actually synthesized) voice giving the natureand location of the emergency and then goes to step 556 to hang up. Ifthe information does not suggest an emergency then the system goes tostep 548 where it registers under the generic mobile identificationnumber and electronic serial number also shown earlier in FIG. 6.

In step 550 the system will then ask if the registration was successful.If it is then it goes to step 554 to do a burst transmission of the datato the appropriate number and then proceeds to step 556 to hang up.

If the registration was unsuccessful in step 550 the system proceeds tostep 552 and generates a random (or pseudo-random) number delay from 1to 59 seconds and then goes back to step 550 to attempt registration.This is due to the fact that another similar system or the same servicemay be attempting to transmit the medical information at the exact samesecond. Note that this system does not require a batch of MINs. Thisexact embodiment in FIG. 16 allows just the mere waiting for an open“slot”. Of course this can also be combined with the searching forfurther phone numbers as shown in FIG. 12.

This approach can also be used for industrial emergency monitoring. Theterm is here used to refer to many (often unwitnessed) emergencies suchas oil and water spills or factory or forest fires. Before thisinvention, one would have had to pay for a cellular phone account foreach monitoring site. With the instant invention, an enormous number ofmonitoring sites can use the same generic number.

FIG. 17 shows the method of using the instant invention to allow thecell phone to act as a car or house key. The system begins at step 600where the operator is prompted to enter a PIN into the key pad. At step604 the systems asks if the PIN matches the base station database. If itdoes not, then at step 606 we prompt for reentry and go back to step600. If the PIN matches then the system goes on to 612 to transmit apseudo random binary number (PRBN) to unlock the car. As an alternativeto a PIN the system will prompt as many people as there are PINs toenter their home phone number in step 602. At step 608 the system does akeystroke dynamics to verify the identity as shown in FIGS. 13 and 14.Once the identity is verified then the system goes to step 612 totransmit the PRBN to unlock the car or house. If the identity is notverified then the system goes to step 610 to prompt for reentry.

In FIG. 18 is shown the embodiment of the invention for modification toallow police and emergency vehicles to get the attention of theoperator. There is a major problem with people talking on their cellularphones and not hearing emergency vehicles behind them. The systemproceeds as follows. At step 620 the system asks if 10 seconds haselapsed. This is because the system will at every 10 seconds check theemergency vehicle warning transmission. If 10 seconds has not elapsedthen the system at step 622 continues with normal phone procedures. Ifit is time for a 10 second check then the systems proceeds to step 624where it checks for the emergency transmission.

If an emergency warning transmission is detected in step 626 then thesystem goes to step 628 where it asks if the operator phone is connectedto 911. This is very important as criminal usage to spoof a policetransmission could be used to shut off a citizen's cell phone and thusprevent them from making an emergency call. It is important that a 911call be able to bypass the shut off. If the operator is connected to 911then the system proceeds to step 630 where the warning is given.

If in fact the user is not connected to 911 then the system goes to step632 and warns by the synthesized voice of an emergency vehicle anddisconnects the existing call so that the user/driver can focus ondriving out of the way.

FIG. 19 depicts the fax scanning version of the invention. Here chargecoupled device (CCD) scanning array 650 is embedded in linear lens 652.The scanned data is observed in either the “fisheye” lens 654 or in thenormal operating screen 656. With this scanner the phone can eitherdirectly send a fax or, with optical character recognition circuitry,send actual text based on the scanned image.
